摘　　要：相控阵系统的阵元通道间存在幅相差异,会对阵列主副瓣比、波束指向精度的关键性能产生影响,需在使用前校准通道。大型宽带相控阵通常采用远场校准方法,针对其部署复杂、使用不便的问题,本文提出了一种解耦合的自动远场相位校正技术。经实装宽带有源相控阵系统的验证试验,该技术可在远场条件下自动完成通道校准,有效优化了阵元通道的幅相偏差,提高了主副瓣比,改善了波束指向精度。整个校正过程耗时短,具有方便、高效的优点和良好的工程应用前景。There are amplitude and phase differences between the array element channels of a phased array system,which can affect the key performance of the array's main sidelobe ratio and beam pointing accuracy.Therefore,it is necessary to calibrate the channels before use.Large broadband phased arrays usually use far-field calibration methods.To address the issues of complex deployment and inconvenient use,this paper proposes an decoupled automatic far-field phase correction technology.After verification tests on an actual broadband active phased array system,this technology can automatically complete channel calibration under far-field conditions,effectively optimize the amplitude phase deviation of the array element channel,improve the main and side lobe ratio,and improve the beam pointing accuracy.The entire calibration process takes only a few minutes,which has the advantages of convenience,efficiency,and good engineering application prospects.
